Intra-operative extracorporeal membrane oxygenation use in pediatric lung transplantation - the Zurich experience

Abstract

There is a lack of data regarding use of ECMO in children undergoing lung transplantation. We evaluated our experience of ECMO in pediatric lung transplant recipients. All patients (<18 yr) who underwent lung transplants between 1997 and 2011 were included (17 children; nine males; median age 16 yr), and the use of intra-operative ECMO evaluated. Transplant procedures were carried out with intra-operative ECMO in seven children (all bilateral lung transplants). Demographics of ECMO and non-ECMO patients were comparable. One child was already on ECMO pre-operative. Lung graft size reduction was undertaken in five ECMO and four non-ECMO cases, respectively. Five patients were taken off ECMO intra-operatively; the other patients were weaned off ECMO within 48 h post-operatively. Three-months survival was 100%. By 12 months post-transplantation, one patient each died in the ECMO and in the non-ECMO group. At the end of the study, six of seven ECMO cases were still alive (median survival 48.5 months); one patient required a retransplant at 53 months. Our small case series suggests that lung transplant procedures can be safely carried out in selected children on intra-operative ECMO support; however, our pediatric experience regarding this scenario is very limited but probably almost unique.
